Use this information to view specific information about
the compute node, such as compute node hardware features and the dimensions
of the compute node.
Note:
- Power, cooling, and chassis systems management are provided by
the IBM NeXtScale n1200 Enclosure chassis.
- The operating system in the compute node must provide USB support
for the compute node to recognize and use USB media drives and devices.
The IBM NeXtScale n1200 Enclosure chassis uses USB for internal communication with these devices.
The following table is a summary
of the features and specifications of the NeXtScale nx360 M4 compute node.

Attention: As a general consideration, do
not mix standard 512-byte and advanced 4-KB format drives in the same
RAID array because it might lead to potential performance issues.

Particulate contaminationAttention:
- Design to ASHRAE Class A3, temperature: 36°C - 40°C (96.8°F -
104°F), with relaxed support:
- Support cloud such as workload with no performance degradation
acceptable (turbo-off)
- Under no circumstance, can any combination of the worst case workload
and configuration result in system shutdown or design exposure at
40°C
- The worst case workload (such as linpack and turbo-on) may have
performance degradation
- Airborne particulates and reactive gases acting alone or in combination
with other environmental factors such as humidity or temperature might
pose a risk to the compute node. For information about the limits
for particulates and gases, see Particulate contamination.
Note:
- Onboard LSI software SATA RAID supports SATA drives and Solid
state drives (SSD). SAS drives are not supported for software RAID.
The booting and use of internal drives with VMware is not supported
with the ServeRAID C100 (software RAID) controller.
- Chassis is powered on.
- A3 - Derate maximum allowable temperature 1°C/175 m above 950
m.
- The minimum humidity level for class A3 is the higher (more moisture)
of the -12°C dew point and the 8% relative humidity. These intersect
at approximately 25°C. Below this intersection (~25°C), the dew point
(-12°C) represents the minimum moisture level; above the intersection,
relative humidity (8%) is the minimum.
- Moisture levels lower than 0.5°C DP, but not lower -10 °C DP or
8% relative humidity, can be accepted if appropriate control measures
are implemented to limit the generation of static electricity on personnel
and equipment in the data center. All personnel and mobile furnishings
and equipment must be connected to ground via an appropriate static
control system. The following items are considered the minimum requirements:
- Conductive materials (conductive flooring, conductive footwear
on all personnel who go into the datacenter; all mobile furnishings
and equipment will be made of conductive or static dissipative materials).
- During maintenance on any hardware, a properly functioning wrist
strap must be used by any personnel who contacts IT equipment.
- 5°C/hr for data centers employing tape drives and 20°C/hr for
data centers employing disk drives.
- Chassis is removed from original shipping container and is installed
but not in use, for example, during repair, maintenance, or upgrade.
- The equipment acclimation period is 1 hour per 20°C of temperature
change from the shipping environment to the operating environment.
- Condensation, but not rain, is acceptable.
